1943 Map of San Clemente Island North

About this map

North Head Lighthouse stands at the northern tip of San Clemente Island, marking a critical point for maritime navigation within the Pacific Ocean during the early 1940s. This survey, conducted by the Army Corps of Engineers and the Geological Survey, details the island's narrowest point at The Isthmus, where the land constricts between Northwest Harbor and West Cove. The landscape is defined by dynamic coastal features like the Shifting Sands and isolated maritime landmarks, including a Lighthouse overlooking Wilson Cove. Small infrastructural details such as Well 2 and various bench marks indicate the strategic and technical mapping of the island's interior elevations. The presence of Castle Rock and West Rock further highlights the navigational hazards and geological character of this offshore California terrain.
